1,391,919. specification of Application filed January To all whom t mayconcern.:

Be it known that I, LIVINGSTON A. THOMP- soN, a citizen of the UnitedStates, and a resident of Waukesha, in the county of Waukesha and Stateof Wisconsin, have invented new and useful Improvements in MassageApparatus, of which the following is a description, reference being hadto the. accompanying drawings, which are a part of this specification.

The invention relates tus.

In massage treatment it is now common practice to use a motor drivenvibrator but in addition to the vibrator treatment the masseur alsomassages'the patientby what may be termed a pinching process. Thispinching process has thus far been done by hand and it is the object ofthis invention to provide a device, preferably motor driven, foraccomplishing this treatment.

The invention further consists in the several features hereinafter setforth and more particularly defined by claims at the conclusion hereof.

In the drawings: Figure 1 is a vertical sectional view through thedevice embodying the invention; Fig. 2 is a plan view of the device;Fig. 3 isa plan view of the device, parts being removed; Fig. 4 isa planview of the top cover; Fig. 5 is an end view of the upper portion of thedevice.

The numerals 6 designate massaging pads to massage apparaor pinchingmembers. These members have base portions 7 carrying beveled guidetongues 8 slidably mounted in beveled guide slots 9 in the upper end 10of a casing or support 11.

This support has a handle portion 12 having a hollow interior 13, bores14 and 15 communicating with the ends of the interior 13, and acylindrical cavity 16 in its top communicating with the bore 14.

The usual flexible motor driven shaft 17 has its end portion 18 mountedin a coupling member 19 and detachably keyed or otherwise connected to ashaft 20. The member 19 is mounted in the bore 15 and is provided withan annular groove 21 to receive the end of a set screw 22 carried by thesupport to secure said member against withdrawal from said support.

shaft 20 is journaled in the bore 14 and its end 23 is squared. Theshaft 20 is centered in the bottom of the cavity 16.

An elliptical cam block 24 has a squared recess 25 centrally located inits bottom to receive the squared end 23 of the shaft 20 to which it isclamped by a screw 26.

The block 24 has a cam groove 27 therein of elliptical outline in whichpins 28 carried by the bases 7 of the pads 6 are mounted, said pinsbeing spaced from the tongues 8 so as to prevent interference of saidtongues with the cam.

A cover plate 29 is secured to the top of the device and is providedwith grooves 30 to permit free movement ofthe tongues 8 and with slotsor grooves 31- to permit free movement of the pins 28.

With the above construction, the rotation of the shaft 20 causes the cammember to act upon the pins" 28 and through them to move the pads 6toward and away from each other, the shaft 2O being preferably driven atahigh rate of speed. The moving pads being applied to the flesh on theirinward movement cause a pinching of the flesh in imitation of thepinching process heretofore performed by hand.

It is to be understoodthat this invention is not limited to any specificform or arrangement of parts except in so far as such limitations arespecified in the claims.

What I claim as my invention is:

l. In a massaging device, the combination of a support, a shaftjournaled therein, a cam on said shaft, massage members operativelyconnected to said cam and moved thereby toward and away from each otherparallel to the plane of rotation of said cam, and guide means for saidmembers disposed at right angles to said shaft.

2. In a massaging device, the combination of a support having a fiatfaced end, massage members slidably mounted on and moving parallel tothe flat surface of said end, and means for moving said members towardand away from each other.

3. In a massaging device, the combination of a support having a recesstherein, a rotating grooved cam mounted in said recess, and a pair ofmassage pads slidably mounted on said support and provided with pinsrunning in the groove of the cam whereby ward and away from each otheron the move- 10 said pads are moved toward and away from ment of thecam.
